Description

[Detailed Description of the Invention] The present invention relates to an electric switch that is driven to open and close by an actuator, and its purpose is to provide an electric switch equipped with an actuator with little play.

As shown in Fig. 1, a conventional electric switch with an actuator has an actuator 1 with locking pieces 2.2 protruding from both side edges near the tip of the main plate 1, and a body 3, which is divided into two parts. The locking pieces 2, 2 are rotatably engaged with the recesses 5.5 formed in the parts 6, 6, and the push button 4 protruding from the container bodies 3, 3 is pressed and driven to close the container bodies 3, 3. This is to operate the opening/closing mechanism of the electric switch built into the machine.

In this structure, the actuator 1 and the bodies 3, 3 are engaged only by the recess 5 and the locking pieces 2, and due to slight variations in dimensions between the recess and the locking pieces 2, or gaps between them, the actuator 1 The disadvantage was that the runout at the tip of the blade was extremely large.

For this reason, there is another problem in that when the engagement between the recess 5 and the locking piece 2 is strengthened, friction increases and the operating load of the actuator 1 changes.

The present invention has been devised in view of these conventional drawbacks and to improve them.

The electric switch with an actuator of the present invention will be explained below with reference to FIGS. 2 and 3, in which the same parts as those of the conventional example in FIG. 1 are given the same reference numerals.

1 is an actuator, 1a is a main plate, 1b is a notch, 1c is a bifurcated piece, 2 is an engaging piece, 3 is an electric switch body, 4 is a push button, 5 is a recess, 6 is a protrusion, 6a is a step, 7 is an engaging portion.

The actuator 1 consists of a bifurcated piece 1c formed by a notch 1b provided at the tip of the main plate 1a, and engaging elements 2, 2 that are folded back and placed at one end of the bifurcated piece and directed inward toward each other.

Further, the container body 3 is provided with a protruding push button 4, an engaging portion 7 consisting of a recess 5, and a protrusion 6.

The actuator 1 and the container body 3 configured as described above are such that when the actuator 1 is inserted in the direction of the arrow A in the figure, that is, in parallel to the container body 3, the first part of the engager 2 hits the stepped portion 6a, so that the actuator 1 A notch 1b provided in the main plate 1a opens the bifurcated piece 1c, and the engaging element 2 is guided by sliding on the step 6a and engages with the recess 5.

In addition, if the mutual dimensions of the engaging elements 2, 2 are changed, the projections 6 can be used for guiding.

Once engaged, the engaging element 5 will not come off due to the elasticity of the bifurcated piece 1c.

The protrusion 6 is held between the inner edges of the notch 1b.

By pressing the actuator 1 in the direction of the arrow B as shown in FIG. The push button 4 is lowered to operate the opening/closing mechanism inside the container body 3.

The width and length of the notch 1b can be appropriately selected in order to adjust the amount of deflection of the bifurcated IC and the play caused by the gap when the protrusion 6 is clamped.

Furthermore, since the engagers 2, 2 are provided facing inward, the device to the vessel body 3 is carried out while the bifurcated pieces are expanding outward, thereby allowing for play in the dimensions between the protrusion 6 and the inner edge of the notch 1b. The gap can be made sufficiently small so that .

In addition, by folding the forked piece 1c, the length of the bifurcated piece 1c becomes longer, and when the actuator 1 is attached to the vessel body, the bifurcated piece 1c becomes longer.
c becomes more flexible and can be easily attached.

As explained above, the present invention comprises an actuator 1 consisting of a bifurcated IC formed by a main plate 1a and a notch 1b provided at the tip thereof, an engager 2 which is folded back from the bifurcated IC and has an engaging element 2 at one end thereof, and the actuator 1. A container body 3 of an electrical device, which is provided with a push button 4 that is pushed and driven by an actuator 1 protruding from the container body 3, and an engaging portion 7 consisting of a protrusion 6 and a recess 5 near the center is provided at one end of the container body 3. The protrusion 6 of the engaging portion 7 is held between the inner edges of the notch 1b of the actuator 1, and the engaging element 2 is rotatably engaged with the recess 5, at right angles to the main plate pressing force direction and the longitudinal direction. The structure is characterized by suppressing engagement play in the direction, and since the engagement part of the actuator 1 is located closer to the center than the protrusion 6, deflection of the tip of the main plate due to engagement play can be minimized. It is.

Further, the engagement between the actuator 1 and the vessel body 3 is not strengthened, but the play is minimized, and the actuator 1 can be easily attached by only a closing operation.
